The Parlor City has traditionally followed the standards
set by the New York State Department of Transportation. Signals have been
usually green colored, though in 1981, the downtown signals installed
on modular installations were dark brown colored.

What has made Binghamton really stand out is that, in late 2001, the
city retrofitted its signal units (some of which are retro)
with light-emitting diode lenses, designed to save the city money on its
utility costs. This even applied to the Art Deco units that the city still
uses on some intersections. For those who like old signal installations,
the city has them, though there have been many changes over the last 30
years.

An ancient Crouse-Hinds unit is freshened up
with new state of the art lenses.
